DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the mobile phone according to the embodiment, and FIG. 2 is a front view of the mobile phone. In FIG. 1, reference numeral 11 denotes a CPU (central processing unit) that controls each part of the circuit, and 12 denotes a ROM (read only memory) in which a program of the CPU 11 is stored. Reference numeral 13 denotes a RAM (random access memory) for data storage, which is backed up by a battery. The RAM 13 stores musical tone data such as a plurality of incoming melody. As shown in FIG. 2, an input unit 14 is provided with various keys 14c such as an off-hook button 14a, an on-hook button 14b, and a numeric keypad, and a tone switching button 14d is provided on the side of the case. A display unit 15 includes an LCD (liquid crystal) display and a display control circuit.
[0008]
Reference numeral 16 denotes a communication unit which transmits transmission data on a carrier wave from an antenna 17 and demodulates an incoming signal received via the antenna 17 and outputs it to the CPU 11 or the voice processing unit 19. The audio processing unit 19 converts the audio signal output from the microphone 20 into digital data, further compresses it and outputs it as transmission data to the communication unit 16, and converts the audio data output from the communication unit 16 into an analog audio signal. Then, the signal is output to the earpiece speaker 24 via the mixing circuit 22 and the amplifier 23. A musical tone signal generator 25 generates a musical tone signal according to an instruction from the CPU 11 and outputs it to the switching circuit 27. The switching circuit 27 outputs the tone signal output from the tone signal generator 25 to the amplifier 28 or the mixing circuit 22 in accordance with an instruction from the CPU 11. The amplifier 28 amplifies the musical tone signal supplied via the switching circuit 27 and outputs it to the speaker 29.
[0009]
Next, the operation of the above-described mobile phone will be described.
First, the operation at the time of incoming melody trial listening and selection will be described with reference to the flowchart of FIG.
First, the user performs a key operation for instructing an incoming melody selection / trial listening mode with the key 14c of the input unit 14. When this key operation is performed, the CPU 11 detects it and displays the music number and music name of the tone data of the incoming melody stored in the RAM 13 on the display unit 15. Here, when the user operates the key 14c to select a song (step Sa1 in FIG. 3 is “YES”), the selected song number is stored in a specific area of the RAM 13 (step Sa2). If the user has not selected a song, the process of the CPU 11 jumps to step Sa2 and proceeds to step Sa3. In this case, the previously set music number remains in the specific area.
[0010]
Next, in step Sa3, as shown in FIG. 2, the characters "Incoming output selection, usually, earpiece" are displayed on the display unit 15, and it is determined whether or not the tone switch button 14d has been operated by the user. The Here, the user can know from the black mark on the display unit 15 that “normal” is currently selected. If the user operates the musical tone switching button 14d, the process proceeds to step Sa4. In step Sa4, the CPU 11 outputs a switching signal to the switching circuit 27 and switches the black mark on the display unit 15 to the earpiece. Thereby, the switching circuit 27 is switched to the mixing circuit 22 side. When the user does not operate the musical tone switching button 14d, the switching circuit 27 is not switched, and the output of the musical tone signal generator 25 is supplied to the amplifier 28. In step Sa5, it is determined whether or not the user has performed an operation to instruct trial listening using the key 14c of the input unit 14. If the determination result is “YES”, the process proceeds to step Sa6, and if “NO”, the process proceeds to step Sa7.
[0011]
In step Sa6, the CPU 11 reads out the musical tone data indicated by the music number in the specific area of the RAM 13 from the RAM 13 and outputs it to the musical tone signal generator 25. The tone signal generator 25 temporarily writes the tone data supplied from the CPU 11 to the internal memory, then generates a tone signal based on the tone data, and outputs the tone signal to the amplifier 23 via the switching circuit 27 and the mixing circuit 22. To do. The amplifier 23 amplifies the supplied tone signal and outputs it to the earpiece speaker 24. As a result, a ringtone melody specified by the user is generated from the earpiece speaker 24. The user listens to the incoming melody sound by placing the earpiece speaker 24 on the ear. If the user determines that the incoming melody is acceptable, the input unit 14 inputs the end of setting. The CPU 11 receives the input and outputs a switching signal to the switching circuit 27. As a result, the switching circuit 27 is switched to the amplifier 28 side and returned to the normal state (step Sa7).
[0012]
Next, the operation at the time of incoming call will be described with reference to the flowchart shown in FIG.
When an incoming call is received, the communication unit 16 demodulates the incoming signal received via the antenna 17 and outputs the incoming data obtained thereby to the CPU 11. The CPU 11 receives the incoming data, stores the telephone number of the caller included in the incoming data in the RAM 13, and then outputs a ringing tone generation command to the musical tone signal generator 25. The music signal generator 25 receives this command, forms a ringing melody corresponding to the music number currently set in the specific area of the RAM 13, and outputs it to the speaker 29 via the switching circuit 27 and the amplifier 28 (step Sb1). ). As a result, an incoming melody is generated from the speaker 29.
[0013]
Next, the CPU 11 determines whether or not the musical tone switching button 14d has been operated by the user. If it is not operated, the process proceeds to step Sb4. If it is operated, the process proceeds to step Sb3. In step Sb3, the CPU 11 outputs a switching signal to the switching circuit 27. Thereby, the switching circuit 27 is switched to the mixing circuit 22 side, and the incoming melody is generated from the earpiece speaker 24 at a low volume. When the user of the mobile phone listens to the incoming melody and presses the off-hook button 14a of the input unit 14 (step Sb4), the CPU 11 detects this and outputs a ringing tone stop command to the musical tone signal generating unit 25 (step Sb5).
[0014]
Next, the CPU 11 outputs a line connection instruction to the voice processing unit 19 and the communication unit 16. Thereafter, the transmission source and the line are connected, and the audio signal of the microphone 20 is transmitted to the transmission source. In addition, an audio signal based on audio data from the transmission source is output from the audio processing unit 19, and is output to the earpiece speaker 24 via the mixing circuit 22 and the amplifier 23, and sound is produced from the speaker 24 (step Sb6). When the user ends the call and presses the on-hook button 14b (step Sb7), the CPU 11 performs line disconnection processing, and outputs a switching signal when the switching circuit 27 is on the mixing circuit 22 side. It is returned to the normal state (step Sb8).
[0015]
Next, when making a call, when the user inputs the telephone number of the other party through the input unit 14 and presses the off-hook button 14a, the CPU 11 once writes the telephone number in the RAM 13 and then outputs it to the communication unit 16. The communication unit 16 transmits the telephone number on a carrier wave. When the transmitted telephone number reaches the central office and the line connection is established by the central office, a telephone call is then made with the other party via the communication unit 16 and the voice processing unit 19.
[0016]
As described above, according to the embodiment shown in FIG. 1 and FIG. 2, the musical sound generating speaker can be easily changed from the original incoming speaker 29 to the earpiece speaker 24 with a low sound level by simply operating the musical tone switching button 14 d. As a result, it is possible to select and set a musical tone such as a ringing melody without disturbing the surroundings.
[0017]
In the above embodiment, the tone signal is output to the earpiece speaker 24 to reduce the volume. Instead, when the tone switching button 14d is operated, the tone signal volume is decreased. It may be generated from the incoming speaker 29 and the user may listen to the speaker 29 by placing it on his / her ear.
Further, although the above embodiment has been described by taking an example of listening to the incoming melody, the musical sound data is used not only for incoming (phone, mail) sound but also for holding sound, alarm sound, karaoke accompaniment sound, appreciation sound, etc. The invention can also be used for listening to musical tones other than ringtones.
[0018]
